This document discusses wild and crazy things that can be built with Asterisk and open source telephony, as presented by David Troy at Digium Asterisk World 2008. It shares Troy's likes and dislikes, influences including Thomas Jefferson and Walt Disney, and things that are needed less of such as IVRs, PBX appliances, and termination providers. Imagination is said to be more important than knowledge, though a little knowledge doesn't hurt.
